The silverfox Hunslet can be bought as ready to run ,or finished body ready to pop onto a bachmann/hornby class 20, or as a body kit with all paints transfers etc included. As I already had two class 20s I went for the middle option they run well and look well too. The mk2 coaches are handy enough to paint in the blue/grey to match. I will check out what paint I used for you. Look up silverfox models/NIR locos. Ian
